Fluorite
Fluorite forms in cubes, octahedra, and many combinations of crystal shapes. It occurs in numerous colors, can glow under ultraviolet light, and splits cleanly along particular crystal planes. Let it remind you that hidden qualities may appear under different conditions and that boundaries become clearer when you recognize the natural dividing lines.
Reflection
- What becomes visible only under different conditions?
- Where do you need a cleaner boundary?
- What can you separate from without rejecting the whole?
